This game lives up to the theme quite well, it's very polished. The art, music, movement, and sound effects are all great and create a very satisfying experience, but the gameplay is very rough and unrewarding. The slimes have way too much health, and you don't have enough. The moment you enter a slime a little too much you are immediately sucked into its core with no hope of escape. They don't die, and can even deal you damage after you kill them.
Still, the core of the game is quite great, and with just a few tweaks to some stats and the addition of actual death (which is a single line of code) it could be very fun.
